I look many times on google that what is the best tag to set in title for seo, H1 or H2 or H3 In many forums and sites they are asking that you need to put only H2 tag in title and someone ask to put H1 in title and i am confused,

Some body tell me the correct tag for seo in google, or any other search engine.

Sidebar links are site-wide links and counted in every post that's not good, its like making widget or getting sponsorship of website. You just have only 5 to 10 percent of links that added in sidebar. (Its better to add nofollow attribute to these links).

Link from in text of article is more important then side link. Its better to rank your site to get link from article in text, then getting link from site bar.

Search this one in google and use precise language to contact with them. You must write high quality content to get better approval of your posts.
